| Summary: | 52-week box-whisker-mean plots to display long-term trends. A few advanced methods have been proposed as well which been recognized as an important factor in substantiating how binned box-whisker-mean analysis to improve x-y scatter building simulation program to test the new techniques. Use calibration to improve thermostat schedules and architectural coefficient of variation of the root mean squared error. dimensions and shading placement. Several statistical hourly whole-building electricity data and site-specific In addition to the graphical calibration techniques, other include carpet plots and comparative 3-D time-series plots. measured monthly utility data has been utilized for many methods are also reviewed for their appropriateness including methods are also used including indoor temperature of -0.7% and a CV(RMSE) of 23. 1 % which compare favorably of the new calibration procedures were able to produce a MBE on very simple comparisons including bar charts, monthly overwhelmed with data and suffer from data overlap. In order percent difference, mean bias error (MBE), and the percent difference time-series graphs, and x-y scatter plots. plots, 24-hour weather-daytype box-whisker-mean graphs to programs, calibration of simulated data to measured data has rendering as a means of verifying the building envelope Results are presented using a case study building located in show hourly temperature-dependent energy use profiles, and the hourly level. Most of the previous methods have relied thesis presents new calibration methods including temperature to improve upon previously established techniques, this traditional graphical calibration techniques become Unfortunately, at hourly levels of calibration, many of the Washington, D.C. In the case study building, nine months of weather data were measured and used with the DOE-2. 1D well the model fits a real building. Model calibration to With the increased use of building energy simulation with the most accurate hourly neural network models. years. Recently, efforts have reported calibrated models at |
